VEHICLE-WHEEL.

Original 110. 1,272,122, dated July 9, 1918, Serial No. 192,884, filed September 24, 1917. Application for reissue filed April 23, 1919.

To all whom it may concern:

Be it known that I, GUs'rAv ScHADnn, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Imroyement in Vehicle-Wheels, of which the ollowing is a specification.

This invention relates to a vehicle wheel and more particularly to that form of vehicle wheel shown and described in Letters PatentNo. 1,215,924, granted to George S. Gallagher and; myself on Feb. 13, 1917, which type of vehicle wheel is especially adapted for use in motor trucks, although it is understood may be used for pleasure vehicles and-other purposes. r

In the form of the invention shown and described in the Letters Patent aforesaid, the

mechanical features by which the resiliencyin thewheel iseffected comprise a seriesof pins adjustably secured in the felly and innet rim and extending between the inner rim and into a recess provided therefor in a flanged portion of the outer rim together with a spring surrounding each of these rims and extending between the shoulder on the same and the face of the flanges on the outer The strains includingthe side thrust in the useof this form of wheel are likely in time to cause the parts to wear to such an extent as to material-1 impair their functions and consequently ecrease the efliciency of thewheel, and the object of the present invention is to overcome this difliculty. The wheel constructed in accordance with my present invention, Iike theone shown and described in the Letters Patent aforesaid, in-

cludes a hub, afelly, spokes connecting the hub and felly, inner and outer rim members with pneumatic or other 'elding tubes between the same, but instea of employing the a ann yed ins and springs, to which reference has hereinbefore been madeI- now prefer .to employ am-ne r brackets andpins connected to the fate Ofth'e felly, together'with a plurality of voluteisprings', oneend of each of which is connected to a in fixed, in the corresponding bracket while the opposite end is suitably secured theouter rim of the wheel, these placed'in similar positions or inlsets of two placed in opposite Serial No. 292,187.

postions as will be hereinafter more particularly described;

In the drawing:

Figure 1 is an elevation and partial cross section of a vehicle wheel made in accordance with this invention; Fig. 2 is an-enlarged cross section on line 22, Fig.1, and

Fig. 3 is a cross section showing a modifled form of the invention.

Referringparticularly to the drawing it will be seen that a vehicle wheel made in accordance with this invention comprises a hub 10 in which suitable spokes 11 are secured at one end while at their opposite ends these spokes are fixed in a felly 12. Assoe ciated with the felly I employ an inner rim preferably comprising aninner rim member 13 and an inner rim member 14. These innor rim members at one end are ada ted to abut against the side portions o-f the elly 12 and are provided with flanges15 and 16 respectively adapted to engage apart of the face of the folly 12.- In its opposite end the inner rim 13 is provided with a clamp 17 and similarly the inner rim 14: is provided with a clamp 18, these clamps being adapted to grip pneumatic tubes 19 and 20 respectively which are made part of the wheel, in a man ILBP'SlIIlllfLI' to that described in Letters Patent aforesaid, it being understood that any suitable connections may be made between these pneumatic tubes for inflating the same and maintaining an equal pressure within them. The inner rim members may bet-see cured to the wheel in any suitable manner, for example, as shown in the drawing, by bolts 21.

Also associated with the felly and lying against the face thereof between the flanges 15 and 16 I employ a, series of brackets-22.

connected to the telly by means of bolts 26 or otherwise.

I also I employ an outer rim 27 Thisis fitted with side flanges 2,8 and 29 between whi h is a treggl'mgmbsr 39 madeof rubber or any other similar and suitable material. The inner face of the outer rim member 27 is preferably screw-threaded as indicated. at 33 to receive the tube rings 31 and 32, the tube ring 31 being adjustable laterally and employed to receive and maintain in position the outer portion of the pneumatic tube 19, while the tube ring 32 is employed to re:- ceive and maintain in position the outer por tion of the pneumatic tube 20, these tube rings being suitably formed for this purpose. Furthermore the outer-edge of each of these tube rings is preferably rounded, rolled, or turned over, as indicated at 34 and extends appreciably beyond the side of the corresponding pneumatic tube in'order'to protect the same as will be readily understood.

Associated with each of "the brackets 22 I employ a volute spring 35. This spring is preferably made of flat metal, but as will be understood, in some instances maybe made of" round metal. Whenmade of 'flat metal the width of the same is approximately equal tothe distance between the flanges 23 and 2401: the brackets 22 and when made of round metal the diameter thereof is such as to be approximately equal to the distance between these flanges. In either case one end of each spring is securely fixed in the pin 25 secured in the flanges of the bracket with which the-spring is associated, while the opposite end of the spring is secured to the outenrim 27. by bolts 36 or otherwise. As

indicated in Fig. 1 of the drawing I prefer toemploy thebrackets 22 and the springs 35 associated therewith in pairs or sets of two, the convolutions of one spring being set in one direction, while the convclutions of the other spring are set in the opposite direction, the inner ends of the springs being connected to the pins associated with their respective brackets while the outer ends of the springs are made so as to form a lap joint as indicated at 37 in order that the same bolts may be employed to secure the outer ends of each pair of springs together and to the outer rim of "the wheel. However, as illustrated in Fig. 3, the springs may be so connected as to be independent of each other, and the springs so placed that the convolutions of the same are all in the same direction.

In the use of the wheel'as hereinbefore described, it will be apparent that under ordinary circumstances the pneumatic tubes when properly inflated'carry the bulk of the 2 weight of the vehicle to which the wheels are attached and that if for any reason these tubes become deflated the springs are suffi'cient not only to carry the load but to maintain the resiliency of the wheel to substantially the same extent as is obtained in the use of the ordinary pneumatic tires, and

' that'th'e volute springs are adapted not only to'take up the turning strains between the parts of the wheel, but also to provide for resisting side thrust between these parts without causing any detrimental wear on any member of the structure. It will also be noted that the inner rim member so construct-ed that the part, thereof'on either side of the wheel may beremovedindependently of the other, thereby facilitating repairs-or replacing of parts in the brackets on the volute springs connecting the -same and the outer mm. It will also be'u'nd'erstood that instead of beingma'de in -separate parts the outer rim: 27 and the tube rings 31 and 32 may be made as an integral structure.

I claim 1. A tire including an inner land outerf rim, tubes interposed and inflatable there* between, and seats laterally adjustable with respect to the outer rim ftjr' bbdily supporting each tube at its outer'circumfer'encei;

2. In a VBhIClG-Wllfifil and incomblnatron with the felly thereof, an inner rim comprisl; in separable members secured to the-inner secured to the face of the felly between the-j separable members of the inner rim, a cor;

responding number of volute springs, d'e vices for connecting the inner, end off, each volute spring in one of the said-brackets, and means for connecting-,the outer 'end of each volute spring in the'said' eaten-rim,

3. In a vehicle wheel and in combinationwith the fellythereof, an inner'rim'coinpris nected in each side of theout'er and corresponding with one of the separableme'ni bers of the inner rim, a pneumatic tube be tween each of the members'of the inner rim and the corresponding tube ring which to? gether with the said. tube ring andinner rim member are separable independently of the corresponding parts on the otherside of the outer rim, a plurality of volute springs, a corresponding number of brackets eachiconnected to the face of the felly between'thc separable membersof the inner rim, andhaving spaced flanges extendingtherefrom,

a pin secured in thefianges of each bracket;

by which the inner end of one of the said mg separable members secured to the'sides' of'the felly, an outer rim, a't'ub'e ring convolute springs is connected in the bracket,"v

and means for connecting the outerixend of each spring to the said outer'rim v p 4. In a vehicle wheel and in-combination with the felly thereof, an inner rimfcorfh prising separable members secured to the sides of the felly, an outer rim, with the inner face thereof screw-threadedftu'berings;

adapted to be turned in the screw-threaded inner face of the outer rim, therebeing' a tube ring corresponding-to each of theseparable mem elis 0f the inner'rim, 'a-pne'u matic tube between each member of the inner rim and the corresponding tube rin a plurality of brackets each secured to the ace of the felly between the se aralble parts of the inner rim and having anges extending therefrom, a, pin secured in the flanges of each bracket, a corresponding number of volute springs the inner end of each of which is connected to a pin in one of said brackets, and bolts by which the outer ends of the said 10 springs are secured in the said outer rim.

In testimony whereof I afiix my signature.
